In a letter published on the president's website, Iranian President Hassan Rouhani has thanked Supreme Leader Ayatollah Ali Khamenei for approving the nuclear deal between Iran and five permanent members of the UN Security Council. Rouhani’s letter seemed to downplay Khamenei’s “conditional approval” of the nuclear deal Oct. 21, and focused more on using the "win-win" strategy for future prospects of cooperation between Iran and other countries.

Rouhani’s Oct. 22 letter said that Khamenei’s “stamp of approval for the results of the administration and the negotiators … will start a new chapter toward excellence for the Islamic Republic of Iran.” The letter added, “The oppressive international economic, trade, and financial sanctions or the unilateral sanctions by the [UN] Security Council, European Union, and America against the Islamic Republic of Iran, have been eliminated.”

In the letter, Rouhani optimistically said that as a result of the nuclear deal, Iran’s “role as a primary provider of stability and security in the region” has been set. The letter also stated that the “Zionist project” to demonize Iran has failed for the first time in decades.

Rouhani also praised what he called unprecedented accomplishments in international agreements, such as, “for the first time in the history of the United Nations, [nuclear] enrichment by a non-permanent member was directly accepted by the UNSC.” He also wrote that for the first time, “six binding resolutions of the Security Council … have been suspended at once through negotiations and the ‘win-win’ approach of the JCPOA has become a model of resolving peacefully complex world problems.”
